CLOTHING FOR CARDS AND THE LIKE Application filed August 4, 1930. Serial l To. 472,987.

This invention relatesto clothing for cards for .various uses and While for the purposes of the present disclosure the type of clothing will be discussed which is particularly applicable to textile fabrics, it will be understood that such cards may be used for many purposes.

In the usual clothing, the foundation em 'ployed is generally a fabric such as canvas through which the wire points are stapled andwhich is wound or tacked on the cylinders or clamped on the flats.

While this type of clothing has been in long and general use and is more or less standard in type, a great many difficulties have come in spite of constant efforts so do.

One of these difficulties has been that the foundation having the characteristics of fabric had to be tempered and Wound and "stretched and re-wound for even an original installation. After use further re-windings were usually necessary.

Another diiliculty which has been common has been that of the working of. the wire points in the fabric at their base so that gradually slots or elongations of the aperture in the fabric occurred so that the teat were not properly supported at their base and yielded too much to give efiicient carding. Furthermore, due to the local stretching of the foundation loose places occurred known as blisters. At such spots thepoints sometimes rise with the foundation causing them to strike the flats or dolfen- These blisters also provided areas in which the heads of the staples in the under-surface of the foundation -were unsupported and the staples worked looseand the points were withdrawn giving too much clearance of the working surface and frequently when the clothing was removed for re-winding the staples in such areas would fall out and have to be replaced by hand.

The fabric foundation furthermore has had to be made in strips of considerable width in order to get sufficient strength. This increased the spiral of the wind slacing the teeth at a disadvantageous position and causing the fibre to feed laterally to the side of the roll. Furthermore, there has been considerable practicaldifficulty in getting the foundation strips trimmed so as to give close jointsin winding, the tendency be ng either-"to trim too close'tothe teeth which are set in closely adjacent rows and thus not leave sufficient support for thewire edge of contacting turns.

Other materials and fabrics have been attempted, such as leather and like materials, but they have all developed more or less of the troubles above enumerated. Special cloth- 7 ing has also been attempted, such as bent Wire constituting both teeth and backing, this being wound edgewise on the drums or cylinders, but this necessitated a very difiicult winding job and had other disadvantages.

The present invention contemplates a new type of clothing which overcomes these difliculties and possesses certain novel characteristics of very marked advantage. I

Briefly, its concept is that of clothing in I or to out too coarsely leaving too much of a spacing between the marginal teeth at the so that'the entire productis rust-proofened and" all crevices filled and smoothened up. Such clothing, as will be later set forth in the more detaileddescription of the specification has many advantages as will be apparent to those skilled in the art. Notably such clothing being of very considerable strength is provided in relatively narrow strips which makes it possible to put on windings of very gradual spiral and with regular spacing of he teeth due'to the clean cut edge. Increased streng h also makes it possible to use fastenof equiring the frequent fastening as in the of'relatively few inches was not only inconings' only at theends of the strips instead venient, but usually resulted in the damaging of the wire.

As illustrative of the invention there is shown in the accompanying drawing a type of clothing particularly adapted for the carding of cotton, although it will be understood that clothing ofthe type used for wool or for the stripping ofv tobacco or other materials may be prepared in the usual styles and types desired by'difi'erent manufacturers for different purposes. p

In the drawing:

Fig. 1 is an enlarged section through a fragment of a strip of clothing in accordance with the invention.

Fig. 2 is a back view of a portion of a ';trip.

Fig. 3 is a View showing the winding and fastening of such.

Fig. 4 is a view of a single tooth of straight type.

Fig. 5 is a similar view of a single tooth of beaded type.

Fig. 6 is a detail View of the means of fastening the clothing on the drum.

Referring to the drawing, there is indicated at 1 a clothing strip of metal such as soft steel or brass or any other suitable metal or alloy. The strip should be of such material and such thickness as to be sufliciently flexible for winding on a drum or roll and should also be sufliciently ductile to permit the formation of bosses 2 formed by the punching of the holes 3. These holes are punched from what is to be the rear side of the 1sitrip and are adapted to receive the wire tee-t The teeth may be in the form of staples 4 as in Fig. 1, or of single points such as 5 or 6 as shown in Figs. 4 and 5. The holes may be punched in any well-known arrangement, usually in the form of the conventional nog, as indicated in Fig. 2.

In Fig. 2, the heads 4 0i? the teeth 4 are soldered, by tin dipping the entire strip, filling the indentations of the holes 3 and the edges of the heads 4 so that the heads are not only firmly attached to the metallic foundation strip 1, but the whole protected against rust. Our clothing is therefore unafiected by oil or water which frequently damaged the old card clothing.

In the form shown, Fig. 4:, the single tooth 5 has a straight shank and is soldered in place. As shown in Fig. 5, the tooth 6 is headed at 6 and may or may not be soldered as desired.

In Fig. 3, the clothing strip 1 is indicated as wound on a drum D, it being fastened thereto at each end. One end fastening is indicated at 7 This fastening as indicated in Fig. 6 is a screw having a conical head, the

clothing strip 1 being punched with a downturned boss 1 which enters a conic countersunk seat (Z in the drum D. Our metal clothing may also be made by electrically welding wire pins or staples to the foundation strip.

As the metal clothing seat is not subject to stretching or shrinking, it is capable of being tightly wound on the drum D or clamped in a flat. On the drum or cylinder it is usually only necessary to fasten the strip at the ends, thus doing away with the frequent tackings such as have been heretofore necessary. In this way the-clothing can be put in position without danger of disturbin the spacing of the teeth or of bending or de orn iug them. As the clothing is prepared, in carefully gauged strips with even edges, it is possible to put on the winding so as to have the adjacent teeth of contacting edges exactly spaced so that when a roll is clothed its entire surface is completely and uniformly covered.

Due to the rigid mounting of the teeth in such a clothing, and due to the thinness of the foundation, it is possible to have a maximum effective length of tooth and possible to have such teeth straight or of low angularity as may be desired. While such teeth can be made with a bend, the straight tooth at present preferred by most users can be used with full effect. These teeth have suflicient resiliency without being subject to deformation and the clothing is very easily repaired and the teeth replaced if for any reason it should become damaged.

Variousmodifications may, of course, be made in the construction and arrangement of the strips and teeth. The holes may be variously punched and the teeth either in staple form or in single form variously set in such foundation and attached thereto by soldering, swaging or other means as may be desired.

- What we therefore claim and desire to secure by Letters Patent is I 1. A clothing for cards and the like, comprising a foundation member of thin flexible metal having apertures punched therein, reinforcing metal collars about said apertures and metal points in said collared apertures, said foundation member, said collars and said points all being coated with a sealing material whereby all parts are bound to each other in unitary assembly. 7

2. A clothing for cards and the like comprising a foundation member of thin flexible metal having apertures punched therein, reinforcing metal collars about said apertures and staple shaped metal points lodged in each pair of said collared apertures, said foundation member, said collars and said points all being coated with a sealing material whereby all parts are bound to each other in unitary assembly.-

In testimony whereof we aflix our signatures.
